Definitions

  • the present invention is generally directed to systems and methods for intravenous (“IV”) delivery, by which fluids can be administered directly to the vascular system of a patient. More particularly, the present invention is directed to IV catheter systems and methods that facilitate insertion into the patient and/or motion from an insertion configuration to a fluid delivery configuration in which fluid can be delivered to the patient through the IV catheter system.
  • An IV catheter system according to the invention is used broadly herein to describe components used to deliver the fluid to the patient, for use in arterial, intravenous, intravascular, peritoneal, and/or non-vascular administration of fluid. Of course, one of skill in the art may use an IV catheter system to administer fluids to other locations within a patient's body.
  • Known IV catheter systems and methods have a number of deficiencies. Many such systems require the clinician to use two hands to position the IV catheter system and/or insert the needle into the fluid delivery location on the patient (for example, the vein into which fluid is to be delivered). Further, many such systems require the clinician to use two hands to move the IV catheter system from the insertion configuration to a fluid delivery configuration, in which the needle is removed from the cannula to permit fluid to be delivered to the vein through the cannula. Thus, the clinician is required to stabilize the patient's arm or other body part having the fluid delivery location prior to insertion of the IV catheter system. As a result, extra time is required for the clinician to initiate transfusion. Further, the clinician is unable to perform any other task, such as stabilizing or reassuring the patient, during insertion and/or motion to the fluid delivery configuration.
  • Embodiments of the present invention are generally directed to an IV catheter system with enhanced ergonomics.
  • the IV catheter system may be inserted and moved toward the fluid delivery configuration with only one hand. Moving the IV catheter system toward the fluid delivery configuration may facilitate “hooding” of the needle.
  • a diameter of a targeted vein may be relatively small compared to a gauge of the needle.
  • a process of hooding the needle involves maintaining a stationary position of the partially inserted cannula while simultaneously withdrawing the beveled portion of the needle into the inner lumen of the cannula.
  • the cannula may be advanced into the vein to a desired position. With the needle hooded, there may be no danger of damaging the vein while advancing the cannula.
  • the beveled portion may be withdrawn into the inner lumen of the cannula such that the beveled portion is at least proximate the tip of the cannula.
  • the needle extending through the cannula and at least proximate the tip of the cannula may provide increased rigidity as the cannula is advanced into the vein.
  • the securement platform may be positioned to receive first contact from the first digit of the hand of the user to urge the catheter hub distally.
  • the first digit of the hand may include, for example, a thumb of the user.
  • the grip of the needle component may be positioned to receive second contact from the second digit of the hand simultaneously with receipt of the first contact such that the first and second contacts cooperate to move the IV catheter system from the insertion configuration toward the fluid delivery configuration.
  • the second digit may include, for example, an index finger of the user.
  • the grip may include an upper surface. In some embodiments, the upper surface of the grip may receive the second contact. In some embodiments, when the IV catheter system is in the insertion configuration, the upper surface of the grip may be coplanar with an upper surface of a particular wing of the securement platform. In some embodiments, a distal end of the grip may contact a proximal end of the particular wing when the IV catheter system is in the insertion configuration. The upper surface of the particular wing may receive the first contact.
  • the grip may include a support surface. In some embodiments, when the IV catheter system is in the insertion configuration, at least a portion of a bottom surface of the particular wing may contact the support surface. In some embodiments, the grip may include a stop surface, which may separate the upper surface of the grip and the support surface. In some embodiments, when the IV catheter system is in the insertion configuration, the proximal end of the particular wing may contact the stop surface. In some embodiments, during motion of the IV catheter system from the insertion configuration toward the fluid delivery configuration, at least a portion of the bottom surface of the particular wing may slide along the support surface.
  • the grip may be disposed on a side of the needle hub.
  • the needle hub may include at least one gripping protrusion, which may be disposed proximal to the grip.
  • a particular gripping protrusion may be disposed on an opposite side of the needle hub as the grip.
  • the particular gripping protrusion may be positioned to receive third contact from a third digit of the hand of the user.
  • the third digit may include, for example, a middle or ring finger of the user.
  • an actuator button may be depressed to move the needle into the needle hub such that the needle is entirely enclosed within the needle hub in the fluid delivery configuration.
  • the actuator button may be disposed on a top portion of the needle hub, which may facilitate easy access of the actuator button and prevent blocking of the actuator button by the first digit and/or the second digit.
  • the actuator button may be disposed between the first wing and the second wing.
  • the IV catheter system may include any catheter system that includes a needle retractable into a needle hub.
  • the IV catheter system may include the AUTOGUARDTM shielded catheter commercially available from Becton, Dickinson, and Company.
  • the IV catheter system may include any catheter system that includes a needle movable from a first position when the IV catheter system is in the insertion configuration, to a second position when the needle is hooded and the IV catheter system is transitioning from the insertion configuration to the fluid delivery configuration, and to a third, retracted or enclosed position when the IV catheter system is in the fluid delivery configuration.

  • the IV catheter system 100 may be connected to a supply of fluid to be infused.
  • the fluid supply (not shown) may include a bag of blood or medication to be delivered to the patient, a drip chamber that regulates flow of the fluid to the IV catheter system 100 , and/or other components involved with the supply of fluid to the IV catheter system 100 .
  • the IV catheter system 100 may have a number of components, as shown in the exemplary embodiment of FIG. 1 . These components may include a catheter component 102 , a needle component 104 , an extension tube 106 , a clamp 108 , and/or a luer lock adapter 110 .
  • the catheter component 102 may be inserted into the fluid delivery location in the patient in order to convey the fluid to the patient.
  • the needle component 104 may facilitate insertion of the catheter component 102 to the fluid delivery location.
  • the extension tube 106 may convey the fluid to the catheter component 102 .
  • the clamp 108 may be used to manually block fluid flow to the catheter component 102 when it is desired to stop or pause fluid delivery.
  • the luer lock adapter 110 may be readily connected to the fluid supply, for example, via connection to a complementary luer lock (not shown) of the fluid supply.
  • the IV catheter system 100 may be an integrated IV catheter system, as the extension tube 106 is pre-attached to the catheter component 102 .
  • IV catheter systems of various open, integrated, and/or safety integrated configurations may be used.
  • the catheter component 102 may have various components, which may include a catheter hub 120 , a securement platform 122 , an extension tubing junction 124 , and a cannula 126 .
  • the catheter hub 120 may have a generally tubular and/or hollow conical configuration, and may have a proximal end 130 and a distal end 132 .
  • the catheter hub 120 may be shaped to define a chamber 134 through which the fluid flows to reach the fluid delivery location.
  • the catheter hub 120 may have a needle port 136 at the proximal end 130 .
  • the chamber 134 may contain a septum 138 that is designed to block flow of blood and/or the fluid to be delivered from the chamber 134 through the needle port 136 .
  • the cannula 126 may be secured to the distal end 132 of the catheter hub 120 .
  • the securement platform 122 may have a generally planar configuration designed to permit the securement platform 122 to be secured to the skin of the patient, proximate the fluid delivery location, to keep the catheter component 102 securely in place as fluid delivery takes place.
  • the securement platform 122 may have a first wing 140 with a generally planar shape, and a second wing 142 that also has a generally planar shape generally coplanar with the first wing 140 .
  • the second wing 142 may be positioned on the opposite side of the catheter hub 120 from the first wing 140 .
  • the first wing 140 and the second wing 142 may extend outward in opposite directions from the catheter hub 120 .
  • the first wing 140 and the second wing 142 may both be fixedly secured to the catheter hub 120 , and may each have a generally triangular shape when viewed from along a direction perpendicular to the securement platform 122 .
  • the first wing 140 and/or the second wing 142 may have any shape, including but not limited to polygonal shapes such as triangular and rectangular shapes, and non-polygonal shapes such as circular, semicircular, oval, oblong, and irregular shapes. Some examples of these alternative shapes will be shown in subsequent embodiments.
  • the first wing 140 and the second wing 142 may each have a trailing edge 144 oriented toward the proximal end 130 of the catheter hub 120 .
  • the needle component 104 may have a needle hub 150 , a grip 152 , and a needle 154 .
  • the needle hub 150 may be detachably coupled to the catheter hub 120 of the catheter component 102 .
  • the grip 152 may extend outward from the needle hub 150 .
  • the needle 154 may be removably positioned within the cannula 126 such that the needle 154 facilitates the process of accessing the fluid delivery location (for example, a vein) and proper positioning of the cannula 126 to deliver the fluid to the fluid delivery location.
  • the needle hub 150 may have a generally tubular shape with a proximal end 160 and a distal end 162 .
  • the needle hub 150 may have a boss 164 positioned at the distal end 162 ; the boss 164 may be insertable into the needle port 136 of the catheter hub 120 of the catheter component 102 .
  • the grip 152 may have a generally planar shape that extends outward from the needle hub 150 . When viewed from a direction perpendicular to the grip 152 , the grip 152 may have an oblong and/or partially elliptical shape.
  • the grip 152 , the first wing 140 , and/or the second wing 142 may have one or more grip features 170 , as shown on the grip 252 , which may help provide a secure interface that facilitates gripping and/or moving the grip 152 by hand.
  • the grip 152 may have a leading edge 172 .
  • the IV catheter system 100 may have an insertion configuration, in which the IV catheter system 100 is readily insertable to position the cannula 126 in the fluid delivery location, and a fluid delivery configuration, in which the fluid flow through the cannula 126 is relatively unimpeded.
  • the IV catheter system 100 is in the insertion configuration.
  • the needle 154 is positioned within the cannula 126 to provide a sharpened tip for penetrating tissue and a relatively stiff body that supports the cannula 126 during insertion.
  • the boss 164 of the needle hub 150 is positioned within the needle port 136 of the catheter hub 120 .
  • the needle 154 passes through the septum 138 of the catheter component 102 .
  • the IV catheter system 100 may be inserted into position by positioning the tip of the cannula 126 proximate the fluid delivery location (for example, the patient's vein).
  • the securement platform 122 may be placed on the patient's skin, proximate the fluid delivery location and/or held in the clinician's hand.
  • the catheter component 102 and the needle component 104 may be advanced to push the cannula 126 until the tip of the cannula 126 penetrates the surrounding tissue and reaches the fluid delivery location. If desired, the catheter component 102 may be advanced by pushing a push surface of the catheter component 102 .
  • the “push surface” is a surface that is generally proximally-oriented, and thus can receive contact from the clinician's hand to urge the catheter component 102 and the needle component 104 , together, distally.
  • the IV catheter system 100 may be moved to the fluid delivery configuration. This may be done by withdrawing the needle component 104 proximally from the catheter component 102 . This may initially cause the boss 164 to be withdrawn proximally from within the needle port 136 .
  • the needle 154 may also be withdrawn proximally from the cannula 126 , and then through the chamber 134 , including the septum 138 .
  • the needle 154 may pass out of the chamber 134 through the needle port 136 , thus completing motion of the IV catheter system 100 to the fluid delivery configuration.
  • Fluid flow to the fluid delivery location may now be accomplished by urging the fluid to flow through the extension tube 106 , into the chamber 134 , and through the cannula 126 to the fluid delivery location.
  • the IV catheter system 100 may advantageously be designed to facilitate insertion to the fluid delivery location to be readily performed with a single hand.
  • the clinician may, with one hand, hold the catheter component 102 and the needle component 104 , for example, by grasping the securement platform 122 and the grip 152 .
  • the clinician may then, with the same hand, apply gentle pressure to one or more push surfaces of the catheter component 102 (for example, the trailing edges 144 of the first wing 140 and/or the second wing 142 ) to urge the tip of the cannula 126 to penetrate the patient's skin and ultimately reach the fluid delivery location.
  • one or more locking features may be used to hold the catheter component 102 and the needle component 104 together until the clinician applies a threshold force to move the IV catheter system 100 from the insertion configuration to the fluid delivery configuration.
  • Such locking features may take the form of interlocking features (not shown) between the boss 164 and the needle port 136 , and/or the like.
  • the IV catheter system 100 may be designed to provide visual confirmation of proper placement in a blood vessel.
  • the catheter hub 120 may be translucent to provide visibility into the chamber 134 .
  • the resulting blood flow, or “flash” may be visible through the exterior wall of the catheter hub 120 as the blood enters the chamber 134 .
  • the extension tubing junction 124 and the extension tube 106 may also, optionally, be translucent.
  • the flash may extend through the extension tube 106 to the luer lock adapter 110 .
  • the luer lock adapter 110 may be coupled to the fluid supply in a manner that substantially prevents blood leakage.
  • the IV catheter system 100 may advantageously be designed to facilitate motion from the insertion configuration to the fluid delivery configuration with a single hand.
  • the clinician may, with a single hand, which may be the same hand used to insert the IV catheter system 100 into the fluid delivery location, grasp the catheter component 102 and the needle component 104 and withdraw the needle component 104 proximally from the catheter component 102 .
  • the catheter component 102 may be left substantially in place so that only the needle component 104 moves significantly to move the IV catheter system 100 from the insertion configuration to the fluid delivery configuration.
  • the trailing edges 144 of the securement platform 122 may act as push surfaces, while the edge 172 of the grip 152 may act as a pull surface.
  • the clinician may place one or more fingers on the leading edge 172 of the grip 152 and pulling proximally, while pushing with a thumb and/or one or more other fingers on the trailing edges 144 of the securement platform 122 .
  • the catheter component 102 may be kept in place with the tip of the cannula 126 at the fluid delivery location while the needle component 104 is withdrawn proximally from the catheter component 102 to unblock the fluid delivery path to the fluid delivery location.
  • the relative positions of the pull and push surfaces may facilitate single-handed operation in the manner described above.
  • the coupling of the needle hub 150 with the catheter hub 120 may be such that the needle hub 150 is rotatable relative to the catheter hub 120 while the IV catheter system 100 is in the insertion configuration.
  • the clinician may, with the hand, rotate the grip 152 to an orientation that is most comfortable for pulling on the leading edge 172 , prior to pulling on the leading edge 172 and pushing on the trailing edges 144 .
  • the septum 138 may have a “low friction” or “low drag” design configured to provide relatively low resistance to withdrawal of the needle 154 proximally through the septum 138 , which occurs as the IV catheter system 100 transitions from the insertion configuration to the fluid delivery configuration.

  • the alignment ridge 280 and the complementary alignment feature may help keep the needle 254 parallel to the cannula 226 during motion of the IV catheter system 200 to the fluid delivery configuration. This may help ensure that the needle component 204 can be smoothly withdrawn from the catheter component 202 . More specifically, application of imbalanced force on the catheter component 202 and/or the needle component 204 may urge the needle component 204 to rotate relative to the catheter component 202 .
  • the alignment ridge 280 and the complementary alignment feature of the first wing 240 may help ensure that such relative rotation does not occur until the needle component 204 has been withdrawn from the catheter component 202 sufficiently to detach the alignment ridge 280 from the complementary alignment feature of the first wing 240 . Thus, binding and/or other undesired interactions between the catheter component 202 and the needle component 204 may be avoided during motion from the insertion configuration to the fluid delivery configuration.
